Setup
1. Charging the Device
Before initial use, fully charge the device. A full charge takes approximately 5 hours and provides up to 30 days of regular use or 180 days of standby time.
- Connect the provided Type-C charging cable to the device's charging port.
- Plug the other end of the cable into a compatible USB power source (e.g., USB port, car charger, power bank, computer).
- The LED indicator light will show charging status. Refer to the device's specific LED behavior for full charge indication.

2. Placement and Installation
Optimal placement is crucial for the device's effectiveness. The device has a range of up to 50 feet.
- Line of Sight: Ensure the device has a clear line of sight to the area where barking occurs. Obstructions like walls, fences, or dense foliage can significantly reduce its effectiveness.
- Indoor/Outdoor Use: The IP65 weatherproof rating allows for both indoor and outdoor installation. Mount it on a wall, fence, tree, or place it in a dog house.
- Avoid Obstructions: Ultrasonic sound cannot penetrate load-bearing walls or glass. For best results, ensure the device and the dog are in the same room or interconnected open areas.

Operating Instructions
1. Powering On/Off
- To turn on the device, press and hold the power button until the LED indicator illuminates.
- To turn off the device, press and hold the power button again until the LED indicator turns off.
2. Selecting Frequency Modes
The Queenmew H1 offers three adjustable frequency modes to suit different dog sizes and to prevent dogs from becoming accustomed to a single frequency. Use the frequency adjustment slider to select the desired mode.

Figure 5: Frequency modes and recommended dog sizes.
- Mode 1 (Low Range): 0KHz-15KHz, suitable for small dogs.
- Mode 2 (Medium Range): 15KHz-20KHz, suitable for docile dogs.
- Mode 3 (High Range): 20KHz-30KHz, suitable for large dogs.
Experiment with different modes to find the most effective setting for your dog or the target dog.
3. Automatic Bark Detection and Training
Once powered on and a mode is selected, the device will automatically detect barking within its 50-foot range and emit an ultrasonic sound. This sound is intended to interrupt the barking behavior.
- Initial Adjustment Period: Dogs may not immediately respond to the ultrasonic sound. An adjustment period of up to 2 weeks is often required for dogs to associate the sound with their barking and modify their behavior.
- Consistency: For best results, ensure consistent use of the device in the areas where barking is an issue.
- Positive Reinforcement: Combine the device's use with positive reinforcement training methods for optimal results. Reward quiet behavior.
Maintenance
Cleaning
- Wipe the device with a soft, dry cloth.
- Do not use harsh chemicals or abrasive cleaners.
- Ensure the ultrasonic emitter is free from dirt or debris for optimal performance.
Battery Care
- Recharge the device when the battery is low to maintain performance.
- Avoid prolonged exposure to extreme temperatures, which can affect battery life.
Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Device not turning on | Low battery; Device not properly charged | Charge the device fully using the Type-C cable. Ensure the power button is pressed and held correctly. |
| Dog not responding to the device | Dog is still adjusting; Incorrect frequency mode; Obstructions blocking ultrasonic sound; Dog has hearing impairment; Device malfunction | Allow up to 2 weeks for the dog to adjust. Try a different frequency mode. Ensure clear line of sight to the dog. Verify the dog does not have hearing issues. Contact support if issues persist. |
| Device not detecting barking | Device out of range; Obstructions; Low battery | Ensure the device is within 50 feet of the barking dog and has a clear line of sight. Charge the device. |
| Short battery life | Frequent activation; Aging battery | Ensure the device is fully charged. Reduce unnecessary activations if possible. Battery life naturally degrades over time. |
